COLLAR-STUFFING MACHINE.

SPECIFICATION forming part of Letters Patent No. 305,166, dated September 16, 188

Application filed November I}, 1883. '(Xo model.)

ing is a specification.

My invention relates to improvements in *collar-stuffing machines, in which a stuffingtnbe is employed by inserting in the rim or tube of the collar and allowing the shuttle or stuffing-rod topass in and deposit the wad or filling at the end of the tube at each motion as the rod is reciprocated.

'My invent-ion will be more fully understood by reference to the accompanying drawings,

' in which Figures 1 and 2 are side elevations showing broken parts. Fig. 3 is aplan view of the same as Fig. 1. Fig. 4 is a side elevation of the same broken part shown in Fig. 1. Fig. 5 is a broken section showing the bottom of the supply-hopper or feed-box, with the rake and operating-cam and the feed or stuffing rod. Fig. 6 is an under plan view of the feed-hopper and the stuffingrod passing forward to take the charge or bundle from the rake. Fig. 7 shows the stuffingrod turned quarter round and passing into the stuffingtube, and Fig. 8 shows an enlarged broken view of the stuffing-rod and the rake.

A represents the frame of the machine; B, the balance-Wheel; C, the driving-pulley; D,

the spur-pinion which operates the spur-wheel E, which is upon the same shaft with and op- ,erates the spur-wheels F and G. The spur- Wheel F gears with and operates the spurwheel H, which is upon the same shaft with and operates the miter-pinion J and the faceplate or crank-Wheel L. The miter-pinion J operates the miter-pinion I, which is attached to and gives motion to the shaft K, which operates the miter-pinion M, which gears with and operates the pinion N and cam O, which operates the rake-yokeP and the rake Q. (Shown in Fig. 5.) The crank-wheel oizface'plate L operates the rake-connecting rod X. (Shown in Figs. 3 and 5.) The spur-wheel G gears with and operates thespur-wheel Y, which is upon the same shaft with and operates the flywheel B. The fly-wheel B operates the 'conmeeting-rod Z, which connects with the stuffing-rod A. The guide pin B operates in the guide-plate O in the guide slot D The connecting-rod Z is connected at the block or cross-head E nected with the cross-head E by a swivel-joint-, which allows it to revolve. The guide-plate G is attached by straps F" to the frame A.

0 represents the extension of the frame A, and is designed to hold the collar 1% while it is'being stuffed.

The clamp G is designed to clamp the collar rim or tube It to regulate the tension, and the guide-clamp H serves as a guide to hold the collar in line and prevent its curving after it has passed off the tube T.

The weights L and M regulate the pressure for the clamps G and H by means of the levers J and K I The following is the construction of my improved collar-stufting machine.

I construct the frame A of metal and the extension 0 of wood, generally of oak, about three inches thick and of sufficient width to receive the collar when stuffing.

The fly-wheel B is sufliciently large to give a five-foot stroke to the stuffing-rod A by means of the pitman or connecting rod Z.

The tube T is made interchangeable, as the size may vary according to the rim or tube of the collar. I generally form it of the metal that is most easily kept clean and bright.

The stuffing-rod U, I generally construct of steel, tapering at the point, so as to withdraw freely after depositing the wad or stuffing. I flatten it and curve or hollow the end, so as to hold the wad, as shown in Fig. 8 at S.

I construct the guide-plate G of metal, and conform the surface to the radius described by the pin B when the stuffingrod A is revolved.

The following is the operation of the machine:- The collar is placed upon the tube T, the tube extending to near the end of the same when opened out, making a length of something like five feet to be stuffed or filled. The clamp G is brought down upon the rim of the collar, and the pulley 0,, being revolved, re-

volves the spur-wheel D, revolving the spurwheels E, F, and G. The spur-wheel G revolves the spur-wheel Y, which is upon the same shaft 100 The stuffing-rod A is 0011- Q as the lly-wheel B, and consequently revolves the same. As the ily-wheel B is revolved, the connecting-rod Z forces the stuffing-rod A forward. At the same time the spur-wheel H, being revolved, revolves the faceplate or crank-wheel L and carries forward the rakerod X and rake Q, taking a bundle which forms the wad. At the same time the miterpinions J, I, M, and N are revolved, revolving the cam O, and the rake Q, carries down the wad or bundle to the point \V' where the stuffing-rod U takes it into the tube T, through the same into the rim of the collar. Before reaching the end of the stroke the pin 13 passes into the groove D and the rod T receives a twist or turn about Onequarter revolution. The pressure of the clamp G" affords friction sufficient to hold the collar and allow it to be stuffed as hard as desired, or it may be increased by adding additional friction by means of the weighted lever L. (Shown in Fig. 2.) The clamp 11* is simply a guide-clamp, and serves to keep the collar straight after it passes out beyond. the stuffing-tube. As the fly-wheel B continues to revolve, the stuffing-rod A is withdrawn and returned to its former position by means of the groove D in the guide-plate 0 thus alternating and taking a wad and placing the same in the rim of the collar at each revolution. The straw is cut to the re quired length and placed in the feed-box Q, where it is fed down to the rake (Q. by its own gravity.

This machine may be readily operated by hand, although I prefer operating it by power and increasing the speed to the full capacity of the straw to stand Without breaking.

Having thus described my invention, What I claim, and desire to secure by Letters Patent,

1. In "collar stuffing machines, the flywheel B and connectingrod Z, in combination with the stuffing-rod A guideplate C having the slot D and operating through the tube T, constructed and operated substantially as and for the purposes set forth.

2. In collar-stuffing machines, the rake Q, in combination with the stuffing-rod A', to opcrate for the purpose of separating the wad or bundle and passing the same through the tube T, substantially as and for the purposes set forth.

3. In collar-stoning machines,themiter-gear J, I, M, and N, cam O, rake Q, and yoke I, in combination with the stuffing-rod A constructed substantially as and for the purposes set forth.

4. In eollar-stuffing machines, the stuffing tube T, in combination wit-h the stuffing-rod A having guide-pin B to operate in the guide-slot D constructed and operated substantially as and for the purposes set forth.
